SWE - Snow Water Equivalent

Side note: It appears that all you lovely people are now on the brink of developing a totally new & unique language, which is based entirely on acronyms. Extremely interesting from an ethnolinguistics perspective, I must say! (but one helluva bugger to learn! The dev team at Rosetta Stone have their work cut out for them!)

But SWE can mean....

SWE - Wikipedia
https://en.wikipedia.org/wiki/SWE
SWE may refer to: Samberigi Airport in Papua New Guinea by IATA airport code; Sensor Web Enablement, an Open Geospatial Consortium framework for defining a Sensor Web; Shallow water equations, a set of hyperbolic partial differential equations; Snow water equivalent · Society of Women Engineers, a non-profit ...

So one needs context - will AI be able to cope ?

SMB - surface mass balance
Doesn't appear in glossary. Abbreviation is used 'all the time' in Greenland Melt thread, and seldom defined there, but is here.

Sorry to be a bother, I think this is a better place to ask than the stupid question thread.

I was reading the end of the 2018 ENSO thread and there's an acronym that I don't understand.

SOI, I'm thinking it's surface ocean index? Maybe... Probably not.

Neven · « **Reply #106 on:** August 15, 2018, 12:42:55 PM »

Southern Oscillation Index.

Tor Bejnar · « **Reply #107 on:** August 17, 2018, 08:08:05 PM »

MSLP - mean sea level pressure
WIPD - whole ice pack detachment

A-Team just used these terms (and defined the second)

The glossary contains mostly Arctic sea ice and cryosphere-related terms, but what the heck, I've added it.

I think its when you have a glacial mountain-pass (saddle) of ice, which as it melts changes water and ice flow to cause a positive feedback on melting.

Or, the description of when an ice sheet reaches a tipping point as it melts. The Laurentide Ice Sheet experienced a saddle collapse over Hudson Bay as it disintegrated into the Keewatin and Labrador sub sheets.

The term "saddle" comes from geography and refers to the landscape shape of a pass between two hills, i.e. like the saddle on a horse.

Re: saddle collapse

I have posted on this b4:

https://forum.arctic-sea-ice.net/index.php/topic,1327.msg107538.html#msg107538

there is an earlier paper from 2012, doi:10.1038/nature11257 of which i again attach fig 3, since it has value on this thread also.

I note this is mainly a toplogical effect, the area available to melt skyrockets as equilibrium line altitude (ELA) rises toward the saddle.

I think there are more than one glacier threads to discuss this. This thread is for proposing new acronyms for the glossary (mostly focused on Arctic sea ice).

Tor Bejnar · « **Reply #126 on:** May 07, 2019, 06:59:39 PM »

Terms frequently used by AbruptSLR in discussions about Antarctica ice shelf melt (and not explained elsewhere in the Glossary).

AABW - Antarctic bottom water
ABW - Arctic bottom water
ASE - Amundsen Sea Embayment - is roughly the size of the state of Texas and the area is known as the Amundsen Sea Embayment (ASE); it forms one of the three major ice drainage basins of the West Antarctic Ice Sheet, the others being the Ross Sea Embayment and the Weddell Sea Embayment (from Wikipedia) - the ASE includes Pine Island Glacier (PIG) and Thwaites Glacier (at the base and to the west of the Antarctic Peninsula)
CDW - Circumpolar Deep Water
GIS - Greenland Ice Sheet [or course, this is in the Arctic!]
MICI - marine ice cliff instability
MISI - marine ice-sheet instability
PIIS - Pine Island Ice Shelf
SAM - Southern Hemisphere Annular Mode (Wikipedia)

to add DMI - Danish Meteorloglical Institute, usually referring to their chart of average temperature north of 80N. My understanding is that those temperatures are not area-weighted. So small circle at 89N gets as much weight as much larger area at 80N.

There's an Antarctic glossary as well. I've added the Antarctic acronyms there. The rest here.

AMOC - Atlantic Meridional Overturning Circulation

Hi I'm seeing the acronym SMOS in the melt season stream, and I don't know what it stands for. I looked but didn't see it here in the glossary. Probably missed it, but could someone help? Thanks

Here you go David >> https://en.wikipedia.org/wiki/Soil_Moisture_and_Ocean_Salinity

Quote

Soil Moisture and Ocean Salinity, or SMOS, is a satellite which forms part of ESA's Living Planet Programme. It is intended to provide new insights into Earth's water cycle and climate. In addition, it is intended to provide improved weather forecasting and monitoring of snow and ice accumulation

oren · « **Reply #132 on:** June 14, 2019, 03:34:16 PM »

SMOS is known in these parts for the Uni Bremen sea ice thinness product (with some caveats, mostly reliable during winter, but showing surface wetness in summer).

I also look at lots of other stuff from the Danish Meteorological Institute:-

I am sure there is loads of other stuff there as well.

"The ECMWF has got ridiculously warmer than 00Z, but at least confirms the WAA over ESS (now getting really deep by day 5) and then stuff that may flop in next run"

WAA?

Warm Air Advection (a more scientific sounding term than 'balmy winds'

). Added now.

Sterks · « **Reply #138 on:** July 06, 2019, 09:53:03 PM »

Warm Air Advection. I use it when the isobars are really tight in the direction from the continent toward the ice, and lasts a few days, but is used everywhere apart from the Arctic

the model run is NOT breaking down the effect from the FSW (earlier post wrt Judah Cohens tweet)

Does anyone know what FSW stands for?

Sterks · « **Reply #141 on:** July 06, 2019, 10:15:13 PM »

WAA is short
FSW, no idea. Freaking Sudden Warming? It is a hell of a heat wave
Final Stratospheric Warming?

Rod · « **Reply #142 on:** July 06, 2019, 10:35:45 PM »

Below is the tweet from Judah Cohen. It was quoted in post 3284 in the melting thread.

I was also trying to figure out what FSW means. I think Lord Vader will need to tell us. But, Sterks’ second guess seems reasonable.

Sterks · « **Reply #143 on:** July 06, 2019, 10:44:33 PM »

Yeah, the Final Stratospheric Warming started before the summer, and it seems polar Stratospheric temps should be normal by now, but remained high during the summer. This apparently helps to maintain high geopotential levels over the Arctic keeping polar vortex away (and lows away). Now it may end, expect more storms entering the pack. That's how I(half) understand it

Tor Bejnar · « **Reply #144 on:** July 07, 2019, 04:16:25 AM »

FSW from here
Fsw = Daily average solar radiation in W/m^2.

F_SW = the solar insolation at the top of the atmosphere [note: it is "F" _{sub "SW"} ]
from here - used 17 times in that paper (This paper referenced in 2017 by rboyd)

and in context:

Quote

The annual-mean incident solar radiation at the top of the atmosphere (F_SW) varies significantly over the Arctic Ocean latitudes ranging from about 210 W m^-2 at 65^oN (roughly the latitude of Bering Strait) to less than 175 W m^-2 at the North Pole.
